Upload up to 1000 files directly from the user interface using drag and drop, or upload larger batches in bulk using SFTP. However, both options require proper file naming and uploading the files in the correct order. or
Main file first (image or animated gif)
Subfiles next
Metadata (renamed JSON or Placeholder.csv) last. Maintain this order even if you modify the project, especially with the placeholder.csv method.
For instance, uploading a file named "Token #0001.jpeg" will result in the following naming:
The asset_name/token name of the file will be "token0001".
The display_name (the name of the NFT) will be "Token #0001".
After a correct naming of the files you can start to upload the files
To add a subfile to an existing File/Token with the name "Token #0001", you need to upload a file named "Token #0001.subfile.1.png". This file will be added to the NFT as the first subfile.
If you want to add more subfiles, you can name them "Token #0001.subfile.2.png" for the second subfile, and "Token #0001.subfile.3.png" for the third subfile, and so on.
To make sure everything works correctly, you need to name your files in a certain way. The names of the files will determine the and for the token. It's important to name subfiles and metadata properly too.
The main file must be an image or animated gif, because this file will be taken as thumbnail in wallets, explorers and on secondary merkats. It may make sense to upload a downscaled version here and the full scale version as for a faster loading time on above mentioned platforms.
We recommend that the numbering of your tokens rarities are not related to the token numbers. If this needs to be the case, we recommend that the of an asset does not correlate in any way with the and is randomly generated. Please use the to override the display names of your tokens. The reason for that is simple; if you are going to use in your project, the buyer could see the (not the ) in the transaction when he is signing the payment transaction. Therefore, a buyer could decide to cancel the transaction if he sees an "not rare/common number" and start over again.
The uploaded metadata must be in the correct . It is allowed to contain placeholders like <policyID>, <asset_name>, <display_name>,<ipfs_link>,<mime_type> as these data is already given with the upload of the token and creation of the project. If you want, you could also .
It is important that .json files are renamed to .metadata files. Please make sure in the detail info of your file that the suffix is not ".metadata.json." If you upload a file named "Token #0001.metadata", the previous uploaded File/Token with the name "Token #0001" will take this file as metadata (in the).
The easiest method to upload metadata in bulk is the . It allows you to use a spreadsheet that contains all metadata of your tokens to add them to your tokens in your project.
